The combination of Active Steering on the front axle and rear axle steering
unique the world over benefits the car’s comfort and agility all in one. And in
addition to the extra stability ensured in this way in fast directional manoeuvres,
Active Steering makes braking manoeuvres even smoother and more superior.
Combining Active Steering with the DSC Dynamic Stability Control sensors, the
system prevents the car from swerving out of control when braking on different
surfaces left and right (modal split) by intervening specifically in the steering as
required.
Superior handling ensured by high-performance brakes and DSC.
The compound brake system in the BMW 5 Series Gran Turismo ensures
excellent stopping power under all conditions, bringing the car to a safe halt in
a short distance even from high speeds. Inner-vented brake discs and swing
callipers optimised for maximum efficiency on the front and rear wheels ensure
extreme resistance to fading and maximum brake comfort.
The brake discs are special lightweight units with the friction ring riveted on to
the aluminium cover. This principle patented by BMW and now also used by
other car makers, together with the aluminium callipers in frame design on the
front axle, significantly reduces unsprung masses and prevents any deformation
of the discs under high temperatures even when subject to extremely high loads
acting on the brake system.
The brake system is supported by DSC Dynamic Stability Control with its wide
range of individual functions. Over and above the stabilising effect provided
by DSC, the system offers further functions promoting both safe and dynamic
driving qualities. These include ABS anti-lock brakes, ASC Automatic Stability
Control, Trailer Stability Control, CBC Cornering Brake Control as well as DBC
Dynamic Brake Control automatically maximising brake pressure on both axles
as soon as this function realises that the driver wishes to slow down as quickly
as possible.
Under extremely high brake temperatures an appropriate increase in brake
pressure prevents any loss of brake power commonly referred to as fading, thus
giving the driver almost the same level of consistent brake power and behaviour
at all times.
Regular Dry Braking optimises brake performance in the wet, while the Brake
Standby function builds up moderate brake pressure as soon as the driver
abruptly takes his foot off the gas pedal, ensuring spontaneous brake action
whenever required. The Start-Off Assistant helps the driver set off smoothly on
